Scroll compressor eccentricity regulating mechanism and scroll compressor

Abstract

The invention relates to a scroll compressor eccentricity regulating mechanism which comprises a crankshaft and an eccentric bushing correspondingly arranged with the crankshaft; the crankshaft comprises a main shaft capable of being corresponding to a motor and an eccentric shaft eccentrically arranged relative to the main shaft; the eccentric bushing is sheathed on the eccentric shaft and is rotationally connected with the eccentric shaft; the surface, enclosed on the side surface of the main shaft, on the eccentric bushing is a first abutting surface, the first abutting surface is providedwith a first tangent plane in an eccentricity angle limiting position, and the side surface of the main shaft is provided with a second tangent plane in an eccentricity angle limiting position; and when the eccentric bushing is rotated to the eccentricity angle limiting position relative to the main shaft, the first tangent plane is matched with the second tangent plane. In the eccentricity anglelimiting position, the crankshaft is in surface contact with the eccentric bushing, so that the situations of contact surface deformation caused by excessive extrusion stress and blockage are avoided.

Description

technical field [0001] The invention relates to the field of compressors, in particular to an eccentricity adjustment mechanism of a scroll compressor and the scroll compressor. Background technique [0002] During use, the movable scroll of the scroll compressor rotates relative to the fixed scroll to realize the meshing between the two coil teeth, so as to achieve the purpose of suction, compression and exhaust. In order to avoid the radial sealing problem caused by the gap between the side walls of the two coil teeth, the machining accuracy of the wall thickness of the scroll body is required to be high, which is not conducive to mass production. Moreover, when the scroll compressor is working, abnormal loads such as liquid shock will inevitably occur. Therefore, an eccentric bushing is set between the crankshaft and the movable scroll of the scroll compressor, and the machining error of the wall thickness of the scroll body is compensated by the cooperation between the ...

Problems solved by technology

[0003] Based on this, it is necessary to provide a scroll compressor eccentricity adjustment mechanism and a scroll compressor for the problem that the eccentric bushing is easily stuck between the crankshaft and the eccentric bushing cannot adjust the eccentricity.
